1. An optional McIntosh External Subwoofer Rotary Control,

Model Number R1163,

 is available from your McIntosh

Dealer.

2. Do not connect the Amplifier’s Speaker Negative Terminal

Connection directly to the Vehicle Chassis. Failure to observe
this could result in damage to your Amplifier.

3. It is advisable to place an inline fuse as close as possible to

the battery.

4. For additional connection information, refer to the owner’s

manual(s) for any component(s) connected to the MCC301M
Amplifier.

5. There is a built-in turn on delay which will mute the speaker

output for approximately two seconds when the amplifier is
turned on.

6. It is very important that loudspeaker cables of adequate size

be used in your music system, to ensure that there will be no
power loss or heating. If your loudspeaker cables are 25 feet
(7.62m) or less, use at least 16 Gauge wire size or larger.

7. The MCC301M Line Level OUTPUT is wired as a “Y”

connection with the INPUT to pass the input signals on to
additional amplifiers (keep cable lengths as short as
possible). The McIntosh MX406 Control Center is capable of
driving several additional power amplifiers with no
degradation of the signal.

8. The MCC301M can accept speaker level inputs at its Input

Jacks. Refer to the diagram for
connection.
